“…The θ 13 and hierarchy sensitivity reach of this "magical" set-up is therefore superior to that of most other rival proposals involving Beta-beams [16,28,29,30,31,32,33,34,35,36,37,38,39], and is almost comparable to that possible with a Neutrino Factory [40] at the magic baseline. This tremendous sensitivity of the CERN-INO Beta-beam project to θ 13 and hierarchy comes from a combination of being close to the magic baseline as well as from being sensitive to near-maximal matter effects.…”

We examine the reach of a Beta-beam experiment with two detectors at carefully chosen baselines for exploring neutrino mass parameters. Locating the source at CERN, the two detectors and baselines are: (a) a 50 kton iron calorimeter (ICAL) at a baseline of around 7150 km which is roughly the magic baseline, e.g., ICAL@INO, and (b) a 50 kton Totally Active Scintillator Detector at a distance of 730 km, e.g., at Gran Sasso. We choose 8 B and 8 Li source ions with a boost factor γ of 650 for the magic baseline while for the closer detector we consider 18 Ne and 6 He ions with a range of Lorentz boosts. We find that the locations of the two detectors complement each other leading to an exceptional high sensitivity. With γ = 650 for 8 B/ 8 Li and γ = 575 for 18 Ne/ 6 He and total luminosity corresponding to 5 × (1

“…As a result for equal γ , the energy spectrum of ν e andν e from their decays will be approximately similar. 18 Ne ( 6 He) per year, which seems to be realistic [49]. The Tevatron accelerator can accelerate 18 Ne and 6 He up to boost factors 586 and 351, respectively.…”

Taking the established nonzero value of θ 13 , we study the possibility of extracting the Dirac CP-violating phase by a beta beam facility with a boost factor 100 < γ < 450. We compare the performance of different setups with different baselines, boost factors, and detector technologies. We find that an antineutrino beam from 6 He decay with a baseline of L = 1300 km has a very promising CP-discovery potential using a 500 kton water Cherenkov detector. Fortunately this baseline corresponds to the distance between FermiLAB to Sanford underground research facility in South Dakota.

“…However, matter effects prevent the exact CPT symmetry. Any difference between the oscillation probabilities at the two facilities can be attributed to matter effects and provides clean handles on the measurement of the mass hierarchy [41,66]. In the case of the shortest baseline, L = 130 km, we show the standard combination of the SPL Super-Beam with the γ = 100 18 Ne/ 6 He β-Beam, dubbed SPL-1+BB in figure 3.…”

Numerous modifications of this basic setup have been studied [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50], most of them being different combinations of two basic ingredients: the possibility of accelerating the ions to higher γ factors [51,52], thus increasing the flux and the statistics at the detector, and the possibility of considering the decay of different ions to produce the neutrino beam. In particular 8 B and 8 Li…”

Optimization of neutrino oscillation facilities for large θ 13

Up to now, future neutrino beam experiments have been designed and optimized in order to look for CP violation, θ 13 and the mass hierarchy under the conservative assumption that θ 13 is very small. However, the recent results from T2K and MINOS favor a θ 13 which could be as large as 8 • . In this work, we propose a re-optimization for neutrino beam experiments in case this hint is confirmed. By switching from the first to the second oscillation peak, we find that the CP discovery potential of future oscillation experiments would not only be enhanced, but it would also be less affected by systematic uncertainties. In order to illustrate the effect, we present our results for a Super-Beam experiment, comparing the results obtained at the first and the second oscillation peaks for several values of the systematic errors. We also study its combination with a β-beam facility and show that the synergy between both experiments would also be enhanced due to the larger L/E. Moreover, the increased matter effects at the longer baseline also significantly improve the sensitivity to the mass hierarchy.
